SAFETY SIGNAL Ann MOTOR-CAR CONTROL. j

7 Application filed November 2, 1925. Serial No. 66,301.

To all whom it may concern: 1 Y

Be it known that we, HARLIE T. BAUGHER and JAMEs E. MILUM, citizens of the United States, residing at Trenton, in the county of Grundy and State of Missouri, have invented certain new and usefulImprovements 1n Safety Signals and Motor-Oar Controls, of

which the following is a specification.

Our invention relates to a safety slgnal system for use on hand cars or, gasoline motor cars employed on railroads, and our object is to provide a system of this character for notifying workmen ofthe approach of I their upper'ends' by a bar, 35 having a cena train from either direction in ample time for them to remove the car from the track before arrival of the train.

In order that the, invention maybe fully understood, reference will now be had to the accompanying drawings, in which v Fig. 1 is a broken plan view of a gasoline car equipped with the invention. 7

Fig. 2 is a side elevation of the parts shown by 1.

Fig. 3 is a plan view partly in section of I v end upon a shaft 46 j ournaled in bearings 48 the signal means and associated parts. i

Fig. 4 is an irregular section on line 47- 4 of Fig. 3. 1

Fig. 5 is a diagram of the circuits employed in carrying out the invention.

Referring now in detail to the different parts, 2 designates a car whichmay be of;

any preferred type either hand or motor operated, but in the present instance 'is shown equipped with an engine 4. The car is mounted upon wheels 6 and '8 provided with individual stub shafts 10 and 12, respective ly, to prevent a short circuit across the rails l 16 designates a rocker shaft journaled in bearings 18 mounted upon the car 2. The rocker shaft 16 is provided at its ends with arms 20, to the lower ends of which spring arms 22 are secured. A pair of t'railing contacts 24, preferably in the form of rollers as shown, are journaled in the lower ends of the spring arms 22 and are held in contact with the rails 14'when' a handlever 26, fixed .32 designates. a glass case mounted upon a base 34 secured'upon the car body, prefer ably at the forward portion ofthe seat 36 in order that the signals enclosed within said glass case 32 will be visible to the driver of Y the car 2. Enclosed within thefcase 32 is a 'pair of electromagnets 38, a day signal40,

and a night signal 42. The day signal 40 in. the present instance is in the form of a sema- I phore, while the night signal 421is' prefer ably in the form of an incandescent lamp with a red bulb.

.The electromagnets .38 are connected at 7 trally disposed stud 37 projecting "upwardly through an opening in the top of the case A rubber washer or other suitable cushioning device 41 is interposed between the top of-thecase 32 and the-bottom ofthe nut 39 to prevent the hard surface from injuring the former."

of the latter The signal 40 is fixedly mounted at one i and provided with a fixedly mounted crank 1 through the intermediacy of suitable insulators 60. The armature 58'is pivotally connected to a bracket 62'secured to the poles 64 of the electromagnets 38.

opposite end to the armature 58 of the elecv tromagnets 38, 'but insulated. therefrom The semaphore 40 is normallyheld in raised, or safety position, by the weight of the connecting rod 52, the switch 56 and the armature 58, and the downward movement of the switch 56 is checked by an adjustable contact 65 threaded through a bracket 67 depending from the base 34. The signal lamp 42 is removably cured to the base 34.

i mounted inasocket 66 se-] i The electromagnets 38 are arranged in circuit upon the car 2 and consisting of one of the'roller contacts 24, wire 70,.b attery 72,

a bell 44, the electromagnets 38,"wire 74,

snap switch '7 6, wire 78, andthe other'roller contact 24. -When the foregoing circuit is closed as will hereinafter appear, the bell 44 is energized as is likewise the electromagnets 38, which, through the intermediary connections above described, swings the justedto the position shown on the diagram Fig. 5,, to cutout the. lamp 4:2, and at night is adjusted toengage the vcontacts 86 and 88 for. the purpose of. cutting out the electromagnet' 38 and cutting i-n'the lamp circuit consisting. of one of the roller contacts 2-1, wire 7 0, battery 72, wire 90, contact 86, switch blade 80, contact 88, wire 92, lamp 42, wire 78,,andthe otherroller contact 24:.

Either ofTthe foregoing circuits are closed through wheelsandaxles A and B of a train" or car approachingfrom either direction. As thebell 44: is connected to the wire 70 at a point betweenithe battery 7 2 and the wire 90, said belle/L will be energized when either theelectromagnet circuit or the lamp circuit is closed. The distance-at which the closing of the circuits will be, effected will depend 7 upon the electromotive force of the battery v'72,,iand in practice will be sufici'ent to give the workmen (ample time to remove the car 2ifrom thetrack before arrival of the tra n orvcar.

Inaddition tothecircuits above described,

; provision is'madei forautomatically opening the .car'; engine circuit on the approach of a train, for the. purpose of stopping the en gine 4., As shown on the diagram, Fig. 6, thesenginecircuit comprises a local battery 98 a wire 100 leading from the engine,

frame, the contact 65,.the switch 56, awire 102,.a manual switch 104, and the spark plug 106 Normally the foregoing circuit is closed, but when theelectromagnets 38 are energized. and attract the armature 58 the same, raisesthe switch 56 from the con? tact 65, therebyopening the circuit and stopping the engine 4:.

When it is desired to closely follow a train 1 or another. car, the roller contacts 24: maybe raised from the rails to open theel'ectromagnet and lamp circults above described, or the switch. 56 may be short circuited by throwing the switch i 10a into engagementa with the-contact 105, thereby closing the ensafety, signalsystem: embodying the, advangine circuit independently of said switch 56.

Fromv the foregoing description, taken in connection with the accompanying drawings, it is: apparent that we have provided a tages above pointed out, ,and while. we have shown one form of the apparatus, We reserve the right to all such modifications thereof as properly fall within the spirit and scope of the invention-as claimed Havingthus described our invention, what we claim and desire to secure by Letters Patent, is:

In a signal system of the character described, the combination with a car having its wheels on one rail insulated from the wheels on the other rail, "a signal circuit upon the car embodying rail contacts and adapted to be closed on short circuiting of the rails, mechanism for engaging and dis engaging said contacts from the rails,v a

visual signal upon the car, a shaft upon which said signal is mounted, acrank fixed to said shaft, a connecting rod pivotallysecuredto said crank, an armature, an,element connecting said armature and the connecting rod, and magnetic means connected to the signal circuit and adapted when energized to actuate the armature.

2. In a signal system of the character def" scribed,,the combination with acar having its wheels on one rail insulated from the wheels on the other rail, asignal circuit upon the car embodying rail contacts andfadapted to be closed on shortcircuiting of the rails, mechanism for engaging and disengaging said contacts from the rails, a visual signal upon the car, ashaftupon. whichsaid signal is mounted,acrank fixed to. said shaft, a-

connecting rod pivotallysecuredl to said crank, an armature, a switch connecting. said armature and the connecting'rod, magnetic means in the signal circuit adapted to ac tuate the armature and elfectmovement of the visual. signalfrom safety to danger po- ,sition. and simultaneously open theswitch, and an eng ne circuit controlled by said switch I a a I 3; In a signal system of the character described, the combinatioirwith a car. having,

its oppositelydisposed wheels, insulated from each other, a signal circuit consisting of rail contacts adapted to be engaged and disengaged from the rails, a semaphore, an electromagnet for actuating said semaphore and which is energized by the circuit when the same is closed on short circuiting the rails, anight slgnal circuit connected across the first-mentioned circuit in advance of said A electromagnet, and a manualswitchadjustable to close the first-mentioned I circuit and open thenight circuit, or ad uStable to close the night circuit and effectshort circuiting of that portion of the first-mentioned circuit embodying. the electromagnet.
